design solution |Behind The Bright Lights, LED Drivers Evolve
To Meet New Requirements
By Randall Restle, Newark
high-brightness LEDs can generate usable levels of light with
improved efficiency, longer lifetimes, and smaller dimensions than
conventional light sources. Accurate current control is essential for an
effective LED lighting solution, and a wide variety of LED driver ICs is
available to help engineers optimize their designs.
